Description

Technical Field

[0001] The utility model relates to an auxiliary device for cleaning a disc of a melt filter, in particular to a cleaning and turning structure for a melt filter disc. Background Art

[0002] The melt filter disc, also called a disc type filter element, is applied to the filtration of high-viscosity melt, and has the advantages of strong filtration ability, adjustable filtration area, large filtration surface and large flow rate, high filtration precision, and can be cleaned and reused. The disc type design enables the effective filtration area per cubic meter to be extremely large, realizing the effective utilization of space and the miniaturization of the filtration device. The main filter material is made of stainless steel sintered felt or multi-layer stainless steel sintered mesh. The melt filter discs are divided into two types. Classified by material: stainless steel sintered felt, stainless steel sintered mesh; classified by structure: soft seal (center ring edge wrapping type), hard seal (center ring welding type). Among the above types, the biggest advantage of the stainless steel sintered mesh filter material is high strength and impact resistance, but the dirt holding capacity is low. The advantages of the sintered felt are large dirt holding capacity, long service life, and good air permeability. Therefore, after the melt filter disc is used for a period of time, the filtration performance decreases and it needs to be calcined and cleaned before it can be used again.

[0003] In the disc cleaning industry, when cleaning the disc, both sides need to be cleaned, so the disc needs to be turned over. In the industry, it was previously done manually.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0038] Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0039] In some embodiments, as Figure 1 、 Figure 3 、 Figure 5 and Figure 6 shown, a cleaning and flipping structure for a melt - filtering disc is provided. The flipping structure mainly includes a cleaning tank 100, a clamping sleeve assembly 200, a clamping cylinder 300, and a flipping motor 400. The clamping sleeve assembly 200, the clamping cylinder 300, and the flipping motor 400 are respectively two groups, and are symmetrically installed at the left and right ends of the cleaning tank 100 as a whole, and are used to automatically clamp the disc 500 to be cleaned.

[0040] Specifically, the clamping sleeve assembly 200 is two groups, which are respectively symmetrically installed on the installation table surface 101 at the left and right ends of the cleaning tank 100, and an arcuate clamping arm 203 for clamping the disc 500 is provided at its inner end, and the outer ends are respectively connected to the clamping cylinder 300 and the flipping motor 400.

[0041] During use, a robotic arm of a peripheral device is used to grasp the disc 500 and move it to the top opening of the cleaning tank 100. The clamping cylinders 300 at both ends are synchronously activated to drive the bow-shaped clamping arms 203 on the clamping sleeve assemblies 200 at both ends to tightly press against the disc 500, thereby clamping the disc 500; then the disc 500 is flipped by the flipping motor 400.

[0042] In some of the embodiments, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, the cleaning tank 100 is a square tank structure. To facilitate the installation of the clamping sleeve assembly 200, the clamping cylinders 300, and the flipping motor 400, an installation tabletop 101 is provided on the peripheral of the top of the opening of the cleaning tank 100. And L-shaped mounting plates 102 arranged symmetrically left and right are respectively provided at both ends of the installation tabletop 101, and mounting holes 103 are opened on the vertical plates of the L-shaped mounting plates 102.

[0043] Among them, to improve the cleaning effect of the disc 500, a number of compressed air water-shedding spray nozzles 104 are provided on the peripheral walls of the inner cavity of the cleaning tank 100. The number of the compressed air water-shedding spray nozzles 104 is divided into two groups. Among them: one group is installed at intervals at the upper end positions of the peripheral walls of the inner cavity of the cleaning tank 100, and the spray ports are arranged obliquely downward; the other group is installed at intervals at the lower end positions of the peripheral walls of the inner cavity of the cleaning tank 100, and the spray ports are arranged obliquely upward. The upper and lower surfaces of the disc 500 are respectively rinsed by the two groups of compressed air water-shedding spray nozzles 104 arranged up and down.

[0044] In some of the embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 7 shown, each clamping sleeve assembly 200 includes a guiding sleeve 201, a clamping push rod 202, and a bow-shaped clamping arm 203. Among them: the inner side end of the guiding sleeve 201 is vertically installed on the L-shaped mounting plates 102 on both sides of the cleaning tank 100 by screws, and the inner hole is on the same axis as the mounting hole 103 on the L-shaped mounting plate 102, so as to facilitate the installation of the clamping push rod 202.

[0045] Specifically, the clamping push rod 202 is movably inserted into the guiding sleeve 201, its inner end is located inside the cleaning tank 100, and the outer end is connected to the clamping cylinder 300 and the flipping motor 400; the clamping push rod 202 can be respectively controlled by the clamping cylinder 300 and the flipping motor 400 to perform axial telescoping or rotation.

[0046] To ensure the stability of the clamping of the disc 500, a bow-shaped clamping arm 203 with a specific bow-shaped structure design is adopted. The inner side wall of the bow-shaped clamping arm 203 is a concave arc-shaped end face, and a groove is provided along its length direction on the arc-shaped end face. The outer edge of the disc 500 is embedded in this groove, and the bow-shaped clamping arms 203 arranged oppositely on both sides are used to achieve the pressing of the disc 500. The middle part of the outer side wall of the bow-shaped clamping arm 203 is connected to the clamping push rod 202, and the bow-shaped clamping arm 203 is synchronously driven by the clamping push rod 202 to move axially.

[0047] In some of the embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 7 shown, to achieve the transmission between the clamping sleeve assembly 200, the clamping cylinder 300, and the flipping motor 400. A limit bearing 204 and a clamping push plate 205 are further provided on the clamping sleeve assembly 200.

[0048] Specifically, the inner ring of the limit bearing 204 is fixedly sleeved on the outer end of the clamping push rod 202, and the outer side wall of its outer ring is fixedly connected to one end of the clamping push plate 205; the flipping motor 400 is installed on the outer side wall of one end of the clamping push plate 205, and the outer end of the clamping push rod 202 passes through the through hole on the clamping push plate 205 and is axially connected to the rotating shaft 402 of the flipping motor 400. Starting the flipping motor 400 can drive the clamping push rod 202 to rotate.

[0049] The other end of the clamping push plate 205 is connected to the telescopic rod 303 of the clamping cylinder 300. Starting the clamping cylinder 300 can synchronously drive the clamping push plate 205 and the flipping motor 400 thereon to perform telescopic movement. Since the output shaft of the flipping motor 400 is connected to the clamping push rod 202, the clamping push rod 202 can be simultaneously pushed to perform axial telescopic movement to press or release the disc 500 between the two bow-shaped clamping arms 203.

[0050] In some of the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the clamping cylinder 300 is installed on the cylinder fixing plate 302 through four cylinder fixing rods 301 installed on its periphery, and its front telescopic rod 303 is connected to the clamping sleeve assembly 200, and the telescopic shaft of the clamping cylinder 300 is arranged parallel to the clamping push rod 202 to synchronously drive the clamping push rod 202 to perform telescopic movement.

[0051] In some of the embodiments, such as Figure 1 , Figure 2 , Figure 3 ,Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , the flipping motor 400 is mounted on the outer side wall of one end of the clamping push plate 205 through four motor fixing rods 401 installed on its periphery, and its rotating shaft 402 passes through the through hole on the clamping push plate 205 and is axially connected to the outer end of the clamping push rod 202.

[0052] The flipping motor 400 uses the clamping push plate 205 as the mounting plate and moves left and right synchronously with the clamping push plate 205, so that the flipping action driven by the flipping motor 400 and the tightening action driven by the clamping cylinder 300 operate independently and do not interfere with each other.

[0053] In some of the embodiments, as Figure 6 and Figure 8 shown, to improve the flushing effect of the disc 500, a rotating mechanism 600 is further installed at the bottom of the cleaning tank 100. The rotating mechanism 600 mainly includes a middle rotating shaft 601, a support sleeve 602 and a positioning seat 603. The rotating mechanism 600 drives the disc 500 to rotate during the cleaning process.

[0054] Specifically, the middle rotating shaft 601 is rotatably installed in the support sleeve 602 through a bearing, and its lower end extends downward to a position below the cleaning tank 100; the support sleeve 602 is a hollow tubular structure, and it is vertically installed at the bottom of the cleaning tank 100 by screws at the four corners of the bottom; the positioning seat 603 is a hollow circular ring structure, fixedly sleeved on the top end of the middle rotating shaft 601, and is snap-connected to the hollow fixing ring 501 at the center position of the disc 500.

[0055] In addition, the rotating mechanism 600 further includes a secondary transmission gear 604, a main transmission gear 605 and a driving motor 606. The secondary transmission gear 604 is fixedly installed at the lower end of the middle rotating shaft 601, and it is meshed and connected with the main transmission gear 605 on the side; the driving motor 606 is fixedly installed at the bottom of the cleaning tank 100, and the main transmission gear 605 is installed on the output shaft at its upper end.

[0056] Combined with Figures 1 to 8As shown in the figure, the working principle of the cleaning and flipping structure of the melt filtration disc is as follows: A robotic arm places the disc 500 to be cleaned on the rotating mechanism 600 in the cleaning tank 100, and starts the two compressed air water-cutting spray nozzles 104 to rinse one side of the disc 500; after the rinsing is completed, the robotic arm lifts the disc 500 to be cleaned to the position of the top notch of the cleaning tank 100, and synchronously starts the clamping cylinder 300 to drive the clamping sleeve assembly 200 to tightly hold the disc 500 from both sides, and then removes the robotic arm; then synchronously starts the rotating motors 400 at both ends to control the disc 500 to flip 180°, turning its bottom surface to the top surface; the robotic arm grabs the disc 500, the clamping cylinder 300 drives the clamping sleeve assembly 200 to move to both sides, disengages from the disc 500, and then presses the disc 500 on the rotating mechanism 600; starts the two compressed air water-cutting spray nozzles 104 to rinse the other side of the disc 500.

[0057] In summary, the cleaning and flipping structure of the melt filtration disc drives the bow-shaped clamping arms 203 at the inner ends of the clamping push rods 202 to tightly hold and fix the disc 500 from both sides through the clamping cylinder 300, and uses the flipping motor 400 to drive the clamping push rods 202 to rotate, so as to synchronously drive the disc 500 to flip; the design of the cleaning and flipping structure of the melt filtration disc is simple and reasonable, with a high degree of automation, simple and convenient operation, which can meet the need for rapid flipping of large-diameter discs, and improves the cleaning efficiency of the disc machine.
